Product Overview

The Junyao JY-HS500 is an all-in-one automatic thermal shrink packaging system that integrates an L-sealing station with a continuous-flow heat shrink tunnel — eliminating the need for separate machines and transfer conveyors. Designed, tested, and refined at Xingjunyao Intelligent Packaging Technology's 13,000 m² manufacturing center in Taizhou, Zhejiang, China, this machine has been shipped to over 25 countries since the company's founding in 2014.

What makes the JY-HS500 different from entry-level shrink wrappers is its industrial-grade construction: a stainless steel frame, pneumatic L-sealing blade with PTFE anti-stick coating, and a three-zone infrared shrink tunnel with independent temperature control. Whether you are bundling beverage cans into 6-packs, overwrapping cosmetic gift boxes, protecting books during distribution, or creating tamper-evident seals on food products, this machine delivers consistent, professional shrink quality at 20–80 packs per minute.

Who is this machine for?

  • Food and beverage manufacturers needing retail-ready multi-packs
  • Cosmetic and pharmaceutical companies requiring tamper-evident overwrap
  • Book publishers and print distributors protecting products during shipping
  • Contract packagers handling diverse product formats on a single machine

Key Features

1. One machine, complete solution
The L-sealer and shrink tunnel are permanently integrated, eliminating alignment drift between separate units. Product transfers seamlessly from sealing to shrinking on a synchronized stainless steel mesh conveyor — no jams, no miscuts.
2. Three-film compatibility without compromise
The machine runs PE (polyethylene), PVC, and polyolefin shrink films. Each film type requires different sealing temperatures and tunnel dwell times. The JY-HS500 stores separate recipe profiles for each, so operators switch between film types with one touch on the HMI screen — no manual recalibration needed.
3.Real temperature control, not just a dial
The shrink tunnel uses PID controllers across top, bottom, and side heating zones, maintaining ±3°C accuracy. This matters because uneven heat creates loose corners on packages and wastes film. Our infrared heating elements are the same type used in premium European shrink tunnels — designed for uniform heat distribution and long service life.
4. Built for production environments, not showrooms
The stainless steel open-mesh conveyor belt withstands 200°C continuous exposure without deforming. The ceramic fiber tunnel insulation keeps exterior surfaces safe to touch. L-sealing blades are hardened steel with a replaceable PTFE coating. Every component is sourced with 10+ years of field data behind the selection.
5. Safety and compliance you can document
CE certification with a complete technical file available for customer review. Pneumatic safety guard on the sealing station, dual emergency stops at infeed and discharge, IP54 electrical cabinet. This matters for import clearance and factory safety audits.

Manufacturing Quality & Company Credentials

Every JY-HS500 is built under ISO 9001-aligned quality procedures at our 13,000 m² Taizhou factory, which houses CNC machining centers, laser cutting stations, robotic welding, and dedicated assembly lines. Approximately 100 employees work across these functions.

Pre-shipment testing: Each machine runs a 48-hour continuous operation test with actual products and shrink film before crating. During this test we verify:

  • Sealing blade alignment and cut quality across 10,000+ cycles
  • Tunnel temperature stability across all three heating zones
  • Conveyor speed consistency
  • Safety interlock functionality
  • Package appearance on at least three different product types

Export experience: Junyao machines operate in over 25 countries across Europe, Southeast Asia, the Middle East, Africa, North America, and South America. We understand international logistics, voltage requirements, and local compliance documentation.

Q: How quickly can I switch between PE film for cans and polyolefin film for retail boxes?

With the recipe management system, format changeover takes 10–15 minutes. The HMI recalls all parameters — tunnel temperatures, conveyor speed, and sealing settings — for each product+film combination. Temperature stabilization may add 5–10 minutes when switching between films with significantly different shrink temperatures.

Q: Can the machine handle irregular-shaped products like gift sets?

Yes. The L-sealer creates a fully enclosed film sleeve regardless of product shape, and the shrink tunnel contracts film around complex contours. For products with sharp edges or protrusions, we recommend polyolefin film for its puncture resistance and uniform shrink characteristics.

Q: What's the typical energy consumption for an 8-hour shift?

The 8.0 kW rating is peak draw during tunnel heat-up. Once at operating temperature, the PID controllers modulate heater output, reducing average continuous consumption to approximately 4.5–5.5 kW depending on product size, conveyor speed, and film type. The ceramic fiber tunnel insulation minimizes heat loss.

Q: Do you provide film recommendations or sourcing support?

Yes. We provide detailed film specifications — thickness, shrink ratio, slip coefficient — for each product application during the quotation stage. While we do not sell film, we can connect you with film suppliers we've worked with in your region.

Q: What happens if a machine arrives damaged or has a startup issue?

Our technical team provides remote guidance for initial setup. If a component is damaged in transit, we dispatch replacements via express within 48 hours. For complex issues, we deploy an on-site engineer — our service team has traveled to 25+ countries for installations and support.
